Legal Status of Delta 8 in Illinois

In Illinois, Delta 8 THC's legal status is established under the Industrial Hemp Act, specifically legislated through a series of bills and laws that align with federal regulations, notably the 2018 Farm Bill. Here's a detailed breakdown of the sources and laws that govern the legality of Delta 8 THC in Illinois:

  1. Industrial Hemp Act (505 ILCS 89/5): This act defines "Industrial Hemp" as the Cannabis sativa L. plant and any part of that plant, including the seeds thereof and all derivatives, extracts, cannabinoids, isomers, acids, salts, and salts of isomers, whether growing or not, with a Delta-9 tetrahydrocannabinol (THC) concentration of not more than 0.3 percent on a dry weight basis.

  2. Federal 2018 Farm Bill: The 2018 Farm Bill is a pivotal piece of federal legislation that removed hemp, defined as cannabis (Cannabis sativa L.) and derivatives of cannabis with extremely low concentrations of the psychoactive compound delta-9-tetrahydrocannabinol (THC) — no more than 0.3 percent THC on a dry weight basis — from the Controlled Substances Act (CSA). This effectively legalized hemp at the federal level, thereby allowing for the production, sale, and possession of hemp-derived products, including Delta 8 THC, provided they meet the specified THC concentration threshold.

  3. Sale and Possession Rules in Illinois: Following the federal legalization of hemp-derived products, Illinois law permits the sale and possession of Delta 8 THC products. According to state regulations, individuals over the age of 21 are legally allowed to purchase marijuana and hemp-derived products, including Delta 8 THC, from licensed sellers. This provision was further supported by the state's move to legalize recreational marijuana effective January 1, 2020.

  4. Purchasing Delta 8 THC: In Illinois, Delta 8 THC can be purchased both online and in person from various retailers, including CBD shops and smoke shops. The legal framework in Illinois ensures that consumers have access to a wide range of hemp-derived products, catering to both recreational and medicinal uses.
